Thermage CPT is a device that generates continuous unipolar radiofrequency (RF) heat energy and delivers it to skin that has premature aging signs such as inelasticity, sagginess, and cellulite. The noninvasive and non-ablative heat energy penetrates deep into the treated skin to stimulate the growth of new collagen fibers and the repair of existing collagen fibers at the treatment area. Unlike other skin tightening and rejuvenating devices, Thermage CPT is incorporated with proprietary Comfort Pulse Technology (CPT), which utilizes a pain alleviating mechanism that mimics Transcutaneous Electrical Nerve Stimulation (TENS) therapy. Both CPT and TENS use heat energy that is interspersed with bursts of cryogen to disrupt the normal neural pathway and in turn reduce the severity of pain. The bursts of a cooling effect from the Thermage device also protects the skin from any injuries associated with heat. Thermage 0.25cm² Eye Tip 450 REP is a membrane Treatment Tip that is designed to deliver precise and shallow heat energy in order to tighten and smoothen eyelids affected by wrinkles, droopiness, or inelasticity. Thermage 0.25cm² Eye Tip 450 REP tip consists of a pre-programmed computer chip that ensures this Treatment Tip can only deliver 450 pulses of energy; after the delivery of these pulses, this Treatment Tip must be discarded. The safety and efficacy of this device were assessed by the U.S. Food and Drug Administration (FDA) and is now classified as a Class II device. Thermage devices and Treatment Tips are products of Solta Medical, an American company that specializes in designing energy-based medical devices.
